2 Claims.

This invention relates to improvements in an antirattling device for windows and the like.

It isan object of this invention to provide a novel device which may be positioned in the frame or sash of a window orthe like and is of such construction as to effectually eliminate rattling of the windows.

It is another object to provide a device which may be inserted in a window frame or a window sash or the like in such a way that .it will not only be invisible to the ordinary observer, but also out of reach to him as well, it being sunk into and within the window frame or sash.

A still further object of my invention is to provide a unique device of the character referred to which includes a casing having a movable member associated therewith which is adapted to prevent the window With which the device is associated from rattling while still permitting the window to be movably adjusted as may be desired. As a special feature, the device is adapted to obviate the need for pulleys and weights now commonly employed.

A still further object is to provide an improved antirattling device which may be made more economically and with fewer operations, both with respect to the manufacture of the parts as well as in assembling thereof, than prior devices known in the art. As special features, the parts, once assembled, cannot be readily separated from each other, either accidentally or otherwise.

Devices heretofore known all have the common objection that, in order to operate them, buffer members in the form of rollers have to be used,

. 35 which members, while they may serve to prevent the window from rattling, nevertheless do not always effectively prevent undesirable vertical movements of the windows relative to their sashes.

Accordingly, I have devised novel means whereby these difliculties are overcome and I accomplish this by the provision of a device which obvi ates the need for buffer members in the form of r rollers.

Various other novel features and advantages and other objects of my invention will be hereinafter more fully described and referred to in connection with the accompanying drawing, wherea Fig. l is a longitudinal sectional elevational view of the device of the invention, partially broken away to show certain features thereof;

Fig. 2 is a front elevational view of the device shown in Fig, 1;

Fig. 3 is a perspective view of the device shown in Fig. 1;

Fig. 4 is a longitudinal sectional elevational view of a modified form of the device of the invention;

Fig. 5 is a front elevational view of the device shown in Fig. 4, partially broken away to show certain features thereof;

Fig. 6 is a perspective view of the device shown in Fig. 4; and

Fig. '2 is a cross-sectional View of the device of the invention in association with a window frame and a window stop.

Referring to the drawing more indetail, the invention will now be described. Like numerals refer to like parts in different figures of the drawing. i

A body member or casing, generally designated by ID and more or less box-like in shape, is adapted to be positionedwithin the frame or sash of a window.

For purposes .of convenience in description, the invention will be described with respect to the device confined within the sash S rather than the frame F as shown inFig. 7.

Fitted within the box [0 is what I call a plate or cover member l2. This is adapted to move inwardly and outwardly within the confines of the receptacle I I]. i

The said plate member l2 has inwardly extending ears such as M on the sides thereof to facilitate guided movements thereof. It also is formed to have anoutwardly extending or raised portion I6 intermediate its ends which forms a projection substantially as shown.

It will be noted thataccording to the form shown in Fig. 1 to 3 inc., this projection has a fiat forward surface. This is intended to frictionally engage the window frame for purposes as will hereinafter be made more clear. 40

Hollow guide members l8 are disposed within the receptacle I0 and have their inner ends secured to the bottom wall of the same in some manner, as by means of portions 2|] of the guides being turned over so as to make heads. These guides l8 extend through suitable openings in the platemember l2 and they may have their outer ends also turned over so as to form heads or stops as shown for limiting the outward movement of the plate member. I

Preferably the guides are formed to have countersink portions 22. These are for receiving the heads of screws which may extend through the bores of the guides for fastening the device to the window.

It will be understood, however, that such screws or fastenings are not always necessary inasmuch as the device, when inset in a recess in a window sash or frame in the manner as shown in Fig. '7, cannot possibly be removed when the sash and frame are in assembled relation.

Surrounding the guide members It are coil springs 24 which will have their inner ends engaging the inside of the bottom wall of the receptacle ID and their opposite ends engaging the underside of the closure member i2 substantially as shown. The springs 2 3 tend to urge the plate member l2 outwardly away from the bottom wall of the receptacle. I

The arrangement is preferably such that the plate member to is prevented from moving outwardly beyond a point where the surfaces of its opposite end portions are flush with the top edges of the side walls of the receptacle as shown in Fig. 1.

In the modification shown in Figs. 4 to 5 inc, the same general structure is shown. However, according to this form the opposite side walls of the receptacle It are provided with aligned openings, through one of which the body part of a friction member 30 extends.

A post or stud 32 extends from the inside of the friction member to and through the opening in the opposite wall of the receptacle. The outer end of post 32 may have a turned-over head part 34 as shown.

A coil spring 35 disposed within the casing surrounds the post 32 and is arranged to urge the friction member outwardly to the position shown in Fig. 5. Flanges may be provided on the inside of the member 33 as shown to limit the outward movements of the same.

It will be noted that the post 32 is located between guides i8 and at right angles thereto. Preferably the plate member i2 is a unitary piece of metal, that is bent intermediate its ends to have coplanar opposite end portions and the intermediate projection it.

In operation, when the friction member is urged inwardly against the compression of the spring 36, the post 32 is likewise moved so as to project outwardly beyond the said opposite side wall of the casing.

The structure of the device having been explained, the installation of the above device will now be described.

The device of the invention as shown in Figs. 4-6 inc. is shown in Fig. '7 as being secured to a window sash id containing a pane 52. It will be understood that the device may likewise be turned around and secured to the frame F or parts thereof.

To install the device, the window sash ll! is recessed, as shown, to receive the same. As stated above, screws or the like are receivable through the hollow guides and the countersinks 22 make a perfectly fiat surface for engaging the recess.

The raised portion l6 extends outwardly to yieldingly engage the stile of the window frame as shown. On the other hand the member fi l yieldingly engages the window stop or bead M.

It will be observedthat the frictional surfaces, such as Hi,- It and 3d are relatively flat and have great areas. These areas being sufficiently large are able to frictionally engage the portion of the window frame, sash or stop which they abut and to insure against undesirable vertical movements. By means of properly tensioned springs, window cords, pulleys and sash weights can be entirely eliminated and the windows can be effectively secured in any desired position.

Furthermore, the window sashes are secured in their respective frames in such a manner, by virtue of these devices, that all rattling is effectively eliminated. There is the further consideration that a tight joint is guaranteed so that cold wind and other undesirable elements are not able to gain admission through the tightly sealed joint. As shown in Fig. 7 the sash is yieldingly urged against stop or bead 4-5 by means of spring pressed member 30.

While I have described the invention in great detail and with respect to the present preferred form thereof, it is not desired to be limited thereto since changes and modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is:

1. A unitary antirattling device for the sash anl frame of a window or the like comprising in combination, a single sheet of ietal having relatively angularly disposed bottom wall, side and end wall men'ibers forming a receptacle open at its upper end, guides fixed to and extending upwardly from said bottom wall within said receptacle having stops at their upper ends, a plate closing the open upper end of said receptacle having depending ears slidahly engageable with inner faces of said side wall members and provided with openings slidably receiving said guides whereby said plate is movable towards and away from said bottom wall and is limited in its movement away from said plate by said stops. and springs on said guides urging said plate away from said bottom wall, said plate having a substantially fiat intermediate portion in a plane spaced from the main body thereof to provide a frictional surface for engaging a part of a window.

2. A unitary antirattling device for the sash and frame of a window or the like comprising in combination, a single sheet of metal having relatively angularly disposed bottom wall, side and end wall members forming a receptacle open at its upper end, guides fixed to and extending upwardly from said bottom wall within said receptacle having stops at their upper ends, a plate closing the open upper end of said receptacle having depending ears slidably engageable with inner faces of said side wall members and provided with openings slidably receiving said guides whereby sai plate is movable towards and away from said bottom wall and is limited in its movement away from said plate by said stops, and springs on said guides urging said plate away from said bottom wall, said plate having a substantially flat intermediate portion in a plane spaced from the main body thereof to provide a frictional surface for engaging a part of a window, said guide members having longitudinal openings therethrough for receiving screws for securing the device to a frame or sash parts of a window.
